Question

According to Ampere's circuital law, ______.

Options

• `oint vec"B" * vec"d"l` = I

• `oint vec"B" * vec"d"l = mu_0`I

• `oint vec"B" * vec"d"l = pimu_0"I"`

• `oint vec"B" * vec"d"l = 2pimu_0"I"`

Answer 1

According to Ampere's circuital law, `underline(oint vec"B" * vec"d"l = mu_0"I")`.

Explanation:

The expression for Ampere’s circuital law is `oint vec"B" * vec"d"l = mu_0`I

Where I is the current included in the surface bounded by the line integral.
